Assessing the validity of the structure, conduct and performance paradigm as theoretical framework for the application of competition policy in the long-term insurance sector of South Africa

Abstract:

In the recent past the industrialised world bore witness to staggering growth in the secondary and tertiary sectors of the economy. In the face of this growth process economic theory had to confront new challenges in explaining and interpreting economic phenomena. The complex nature of inter- and intra-firm relationships forced a pragmatic stance on policy makers to ensure that all actions are efficient and competitive. Two prominent schools of thought with contradictory viewpoints emerged. The Structuralists built upon the foundations laid by Bain (1951) and Mason (1939). This implied a theoretical framework, namely the Structure, Conduct and Performance paradigm (SCP paradigm) that could be used to explain inter- and intra-firm relations according to a simple forward causality argument. The Structuralists' interpretation of the SCP paradigm provides strong support for the implementation of deconcentration measures by competition authorities. The Chicago School, however, developed a counter-argument inspired by Demsetz's (1973) efficiency hypothesis. According to them, causality is reversed and deconcentration measures are used at the expense of the most efficient firms. The thesis aims to study these contradictory arguments as well as their evolution in South Africa. Various researchers in South Africa have built on the arguments of the Structuralists and the Chicagoans regarding the manufacturing sector. The theoretical methods implemented by them will be applied to the long-term insurance industry to assess the validity of the SCP paradigm as a theoretical framework for the application of competition policy.
